WEIGHING-SCALE.

Application filed January 28, 1920.

Y 0 all 207mm '52! may concern.

it known that I, JONATHAN S. Jones, a citizen ot the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in VVeighingScales, of which the following is a specification.

This invention relates to improven'ients in weighing scales, particularly adapted though not necessarily limited in its use for weighing out predetermined quantities of material from a supply or bulk, and one of the objects of the invention is to provide an improved device of this character which will be automatic in operation and which will continue to operate without the attention of the operator so long as the bulk or supply of material lasts.

A further object is to provide an improved device of this character having means whereby the quantities measured out or weighed out may be varied at will.

A further object is to provide an improv d device of this character which will be simple, durable, cheap and compact'in construction and eltective and eilicient in operation.

To the attainment of these ends and the accomplishment of other new and useful objects aswill appear, the invention consists in the f ,atures of novelty in substantially the construction, combination and arrange ment of the several parts hereinafter more 'lullv described and claimed and shown in the accompanying drawings illustrating this invention, and in which:

may be of any desired size and configuration and is preferably provided with a discharge outlet 13 of a liberal size and a smaller dis charge outlet opening 1-1, for a purpose to be hereinafter set forth.

A suitable cut-oil is provided for voutrolling the outlet openings 131& and this cut-oil is mounted preferably upon a swing ing support 16 and is adapted to alternately close the outlets 131A as the support 16 is shifted. he support 16 may be mounted pivotal movement in any desired or suitable manner such as by means of pivot pins 17 connected with the wall. of the hopper 12. The support 16 preferably extends for a considerable distance below the hopper and adjustably mounted upon the support 16 is a receptacle or tray 18 which latter is adapted, when the outlet opening 13 is open, to assume a position thercbelow to receive the material from the hopper 12. At the same time when the T8091 tacle 18 is in this posi tion, the cut-oif 15 will assume the position shown in Fig. 5 to close the outlet 1%.

If desired, the receptacle 18 may be mounted for adjustment upon the support 16 in directions toward and away from the hopper by means of suit ble adjusting mechanism embodying a screw or pin 19 coop ing with apertures in the support -6. This :uljustnicnt is provided so that during a predetermined operation of the apparatus, a greater or less quantity of the material from the hopper will be delivered into the receptacle 18 before the latter is dumped in a manner to be hereinafter set forth.

A. scale beam 21 is pivotally and detachably connected with a support or upright in any suitable manner such as by means of a pin and keyhole slot connection 282 i. This scale beam is pivoted intermediate its ends, one end thereof being located adjacent the hopper while the other end 25 is provided with graduations 26 and with which graduations adjustable weight 27 cooperates. This weight is held in its adjusted position upon the scale beam by means of a suitable securing device 28 and if desired, a supplemental and adjustable weight or element may be connected with the weight 27 for the purpose of securing a fine adjustment of the weight with respect to the graduations 26 as is usual in devices of this Connected with the end of the scale beam 21 which carries the graduations 26 is a counter-balance 30 preferably of substantially the configuration shown and this counter-balance is provided as a means for counter-balancing the mechanism and also as a means for returning the parts to a position to receive the material from the hopper.

Connected with the end of the scale beam 21 which is adjacent the hopper 1.2 is a track or runway 31 which is preferably disposed at an angle to the scale beam. This track or runway may be of any desired length and the extremity 32 thereof is deflected or offset so as to form a curved portion at the delivery end of the track, and arranged at the extremity of the track is a stop 33, while a similar stop 34L is arranged at the opposite end of the track.

Mounted to move upon this track or runway is a car or traveling receptacle 35 having an open front end and provided with uprights 3637 respectively carrying the wheels 3839. The uprights 36 are of a length somewhat greater than the length of the uprights 37 so that when the scale beam and parts are in the position shown in Fig. 1 the car or receptacle 35 will assume an inclined position toward the rear so as to prevent the material being delivered thereinto from passing out of the open front end, but when the car travels upon the track or way 31 toward the free end thereof, and as the scale beam moves about its pivot under the influence of the traveling movement of the car, it will be noted that the track or way 31 will be lowered and as it is lowered, it will cause the body portion 35 of the car to assume a substantially horizontal position and will be maintained in this position until the wheels 38 on the uprights 36 en and rest upon the portion 32 of the track 31. This will cause the open front end of the car to be lowered and the material will be discharged therefrom as is more clearly shown in Fig. 5.

The counter-balance 30 together with the weight 37 will maintain the parts normally in the position shown in Fig. 1, but when material is delivered into the car or receptacle 35 from the hopper 12, the material will cause the scale beam 21 to be over balanced and will rock the scale beam together with the track or way 31 in a direction to lower the track or way. During this operation the car or receptacle 35 will travel upon the track toward the outer end there of and will continue to travel until the car is arrested in its movement by the stop 3 lwhich will occur at about the time the track reaches the limit of its downward move ment. This will deliver the material from the car into any suitable receptacle provided for that purpose. When the car is emptied of the material, the weight 27 will over-balance the car and the scale beam will be moved in the opposite direction to raise the track 31 and cause the car 35 to travel by gravity down the track as it assumes an inclined position, until the car is arrested by the stop 34 on the track 31 which will occur when the parts assume the position shown in Fig. 1.

Obviously the weight 27 may be adjusted upon the scale beam to vary or control the amount of material which actuates the car.

Any suitable means may be provided for automatically shifting the cut-oii' 15 and the receptacle 18, but inasmuch as in the present form of the invention the cut-oil? l5 and receptacle 18 are mounted upon the swinging support 16, there may be pro-- vided an arm 10 which may be connected with the support 16 and which arm when the support 16 is in the position shown in Fig. 5 will, when the scale beam is moved to raise the track 31, stand within. the path of movement of the car or receptacle 35 so that as the car moves down the track or way 31 into the position shown in Fig. 1, it will strike the arm 40 and shift the support 16 to open the outlet 14 and close the outlet 13.

During the time that the car or receptacle 35 is bein dumped and while the parts are in the position shown in Fig. 5, the cut oil 15 will be in a position to close the outlet 14. and open the outlet 13. In this position, it will be readily seen that a considerable amount of the material will be delivered from the hopper 12 into the receptacle 18, and when the car or receptacle 35 swings the parts to the position shown in Fig. 1., the material which has been delivered into the receptacle 18 will be deposited into the car 35, causing a large bulk of the material to be quicklv delivered to the car. As the car causes the cut-off 15 to close the opening 13, the smaller outlet opening 1 1- will be opened and will allow only a smaller and finer supply of material to be delivered to the car so as to obtain the exact weight which will cause the loaded car to overbalance the weight 27 on the scale beam.

In order to maintain the car upon the track or way 31, a suitable guide 41 may be provided which is adapted to pass over the axles 42 of the wheels 3839 and which guide 41 is preferably arranged to cotiperate with the body of the track 31 to maintain the axles therebetween.

If desired and in order to limit the swinging movements of the scale beam 21, suitable stops 4l34; may be provided which eotiperate with the upright or support 22.

It is though that the operation of this device will be clearly understood from the foregoing specification, and it will be clearly seen that the apparatus will be automatic in its operation to automatically shift the car 35 to a loading and a dumping position for supplying material thereto so long as there is any material in the hopper 12. i

Obviously all of the parts may be constructed of any desired material and of any suitable size and configuration, and while the preferred form of the invention has been herein shown and described, it is to be understood that various changes may be made in the details of construction and. in the combination and arrangement of the several parts, within the scope of the claims without departing from the spirit of this inven tlon.
